This PR is an example approach how to make optional fields of a secondary type classes really optional.
I wrapped optional fields with boost::optional, right now only in LinkPreviewOptions, ReplyParameters classes.
It solves the problem described in issue #308
There are many such classes in Api, so consider this change as an example approach. Any way, it covers most used sendMessage() function, and solves problem with replies.
